BBC sounds have an enthralling 5 episode podcast about a scam know as OneCoin – a digital cryptobanking currency. I must confess as soon as I heard of Bitcoin my suspicion of how this could be manipulated were raised. But true cryptobanking relies on the system NOT to be manipulated through a convention know as a “block-chain”. Once this is in place you literally cannot tamper with the rates, Essentially this is a form of Networking Marketing. which in turn would be pyramid selling, based on getting more and more to sell a bitcoin so that you in turn get a cut. No doubt people do get rich – but only at the top of the chain. Ayway I found the BBC sounds podcast very entertaining and informative. Remember any get rich quick scheme must be suspect in my opinion.
